You don't put on a seatbelt because you think you're going to crash. You don't pay into a term life insurance policy because you think you're going to die.
Only a crazy person thinks this way.
Only a moron would argue against this.
Q1: Do you believe you're going to crash when you get in a car?
Q2: Do you wear a seatbelt
An analogy that would make sense with the Orangemanbad cult is that the risk of death is high (when it isn't) so we need to install a rollbar cage and wear a neckbrace to drive to the grocery store...
The analogy went completely over your head, and no this isn't an apt analogy.
My analogy made one central point: You do not need for a bad outcome to be probable in order to take steps to ensure protection. This isn't controversial, it's common sense.
The reason that applies is because people like you excuse voting for Trump on the basis that the chances of him plunging us into civil was is "insanely small". Setting aside the accuracy of your characterization, the implication of your statement is that it isn't a disqualifier for a president to be a potential instigator of a civil war. That's absurd.
In any sane rational world the president is expected to be the nation's primary protector of democracy, not the inspiration for it's failure which the rest of the country must guard against. Electing a president who has contempt for democracy is like hiring a bank robber to be the lead security guard for your jewelry store. Sure, he might not pull off a heist, doesn't mean it was a smart choice. Either way you're still an idiot for putting yourself in that situation.
